How It Works

1. API Service: Attempts to fetch usage data from Z.ai's API endpoints
2. Fallback: If no API endpoint is available, uses local tracking
3. Configuration: Stores API key and settings in VS Code configuration
4. Display: Updates status bar with current usage and progress
5. Refresh: Periodically fetches updated data (configurable interval)

API Endpoints

The extension uses the official Z.ai monitor API endpoints:

• https://api.z.ai/api/monitor/usage/quota/limit - 5-hour token quota
• https://api.z.ai/api/monitor/usage/model-usage - Model usage stats (with time range)

Debugging

Run the debug command to see raw API responses:

• Command: Z.ai Usage Tracker: Debug: Show Raw API Responses

Privacy

• Your API key is stored securely in VS Code's encrypted SecretStorage
• Usage data is only fetched from Z.ai's official API
• No personal data or code is sent to external services
• All data processing happens locally

Troubleshooting

"API key not configured"

• Click the status bar item and select "Update API Key"
• Or use Ctrl+Shift+P → "Z.ai Usage Tracker: Configure Settings"

"Failed to fetch usage"

• Check your internet connection
• Verify your API key is valid at z.ai/manage-apikey
• Try clicking "Retry" in the error message
• Run the debug command to see raw API responses
